Examining Suspended Program

Basics

When a breakpoint is hit, or a program execution is manually
suspended, you can
examine your application by analyzing frames.

A
frame corresponds to an active method or function call.
A frame stores the local variables of the called method or function,
the arguments to it, and the code context that enables expression evaluation.

All currently active frames are displayed on the
Frames pane of the
Debug tool window, where you can
switch between them and analyze the information stored therein.

Examining a suspended thread

To examine frames of a suspended thread

Select a thread from the thread selector drop-down list on top of the Frames
pane. The list of frames is displayed:

Select a frame from the Frames list. The Variables pane shows
all the variables available to the method call in this frame, so you can further explore them.

Navigating between frames

Do one of the following:

Use up and down arrow buttons on the toolbar.

Use Up and Down shortcuts.

You do not need to perform any actions to navigate to the frame's source code.
WebStorm automatically jumps to the source code of the selected frame in the editor.
